In modern industry, especially in the food, medical, and cosmetic packaging sectors, the requirements for material performance are becoming increasingly stringent. High-barrier materials are crucial for ensuring product quality, extending shelf life, and reducing waste. Ethylene-VinylAlcohol Copolymer is seen as a great green packaging material because it blocks gases, smells, and solvents so well. It also possesses good processability, transparency, mechanical strength, abrasion resistance, and cold resistance.

 

 

EVOH is a type of thermoplastic resin made from ethylene and vinyl alcohol. A key feature is the many hydroxyl groups (-OH) in its structure. These groups create strong hydrogen bonds, which limit how well gas molecules, like oxygen, can pass through it. This gives EVOH very good barrier properties. It blocks oxygen much better than common polymers like polyethylene (PE) or polypropylene (PP). In fact, EVOH can be thousands of times better at blocking oxygen.

 

1.  EVOH EW-3201: Specifications Overview

Items Specifications
Appearance White transparent particle
Melting index (190℃,2160g/10min) 1.5-2.5
Chroma ≤20
Volatile content(%) ≤0.3
Ethylene(mol%) 30.0-34.0
Density (g/cm3) 1.10-1.20

 

2. In-depth Analysis of Key Physical Properties

2.1 Superior Gas Barrier Performance

The core advantage of EW-3201 lies in its ethylene content, ranging from 30.0 to 34.0 mol%. For EVOH (Extracorporeal Membrane Oxide), ethylene content is a crucial parameter:

  • Lower ethylene content: More hydroxyl groups (-OH) on the polymer chain, stronger hydrogen bond network, and better oxygen barrier performance.
  • Higher ethylene content: Better polymer thermal processability (melt index, flexibility), and improved water resistance, but slightly reduced barrier performance.

EW-3201's 30.0-34.0 mol% ethylene content provides a good thermal processing window while ensuring extremely high oxygen barrier performance. This method is appropriate for packing food items needing strict preservation (like meats, sauces, and milk products) and medical tools needing high levels of cleanliness, which extends how long they can be stored.

2.2 Ideal Processing Performance

The melt index (MI) of EW-3201 is 1.5-2.5 g/10 min, which is a relatively moderate range.

  • Moderate MI: This indicates that its melt viscosity is moderate and its flowability is good, making it suitable for high-speed, complex co-extrusion or lamination processes without excessive degradation during processing.
  • Importance in Co-extrusion: EVOH is typically used in thin layers sandwiched between structural layers such as PE, PP, or PET. The MI value helps EW-3201 match well with typical adhesives and outer layers. This makes for good mixing of multilayer structures and strong sticking between layers.

2.3 High Density and High Transparency

EVOH typically has a high density (1.10-1.20 g/cm³), attributed to its highly ordered molecular structure and strong hydrogen bonds. High density is the structural basis for achieving high gas barrier properties. Meanwhile, a colorimetric index below 20 ensures that films or containers made from EW-3201 possess excellent transparency and gloss, crucial performance for packaging that needs to display contents (such as high-end food and cosmetics).

2.4. Environmental Sensitivity 

It's important to note that the barrier properties of EVOH are sensitive to environmental humidity. Because the hydroxyl groups on the molecular chain are hydrophilic, when environmental humidity (RH) increases, water molecules enter the hydrogen bond network, weakening hydrogen bonding and leading to increased oxygen permeability. 

  • Application Solution: EW-3201 is commonly paired with thermoplastics like PE, PP, and PET in real-world uses. This is done through co-extrusion or lamination to create a multilayer structure. The EVOH layer is placed between polyolefin layers that have good moisture resistance. This effectively protects the EVOH layer from moisture, allowing it to maintain excellent barrier performance even in high-humidity environments.

 

3. Main Applications

  • Food Packaging: Used in the production of oxygen barrier films, cling film, aseptic packaging, tubing, and bag-in-bag systems, significantly extending the shelf life of dairy products, jams, meat, seafood, coffee, and tea.
  • Medical Supplies: Used for aseptic packaging of infusion bags and medical devices, preventing product oxidation and microbial contamination.
  • Industry and Agriculture: Used as an oxygen barrier layer for underfloor heating pipes to prevent pipe corrosion; or for solvent-resistant containers for solvents and chemicals.
  • Cosmetic Packaging: Used in the production of multi-layer cosmetic tubing and containers, effectively preventing the oxidation or volatilization of fragrances, vitamins, and other active ingredients.

 

As the packaging industry needs thinner, more efficient, and greener materials, good ethylene vinyl alcohol (EVOH) products such as EW-3201 (EVASIN EV-4405F) will keep being very important and will push forward barrier packaging tech improvements around the world. Choosing EW-3201 means choosing a high-performance, highly reliable, and sustainable packaging future.

Since the late 1930s, polyvinyl butyral (PVB), a type of thermoplastic resin, has been key to making laminated glass. Laminated glass consists of one or more layers of PVB film (the interlayer) between two or more pieces of glass, bonded together using heat and pressure. This structure endows the finished glass with a range of unique properties, making it a crucial safety and functional material in the automotive industry and modern construction.

 

1. Chemical Basis and Unique Properties of PVB Resin

1.1 Structure and Synthesis

PVB resin is a synthetic polymer obtained from polyvinyl alcohol (PVA) and butyral through an acetalization reaction. Its molecular chain contains three main functional groups:

  • Butyral group: Responsible for providing the polymer with hydrophobicity, elasticity, and solubility.
  • Hydroxy group: Maintains the polymer's strong adhesion to glass surfaces, heat resistance, and compatibility with plasticizers.
  • Vinyl acetate group:,Usually present in small amounts, it has a fine-tuning effect on the glass transition temperature (Tg) and processing properties of PVB. This unique structure endows PVB with a range of ideal properties for laminated glass applications.

1.2 Key Physical Properties

As the interlayer in laminated glass, PVB film must possess the following core physical properties:

  • High Adhesion Strength: Strong adhesion to the glass surface ensures that glass fragments adhere firmly to the film upon impact.
  • Excellent Elasticity and Toughness: Ability to absorb impact energy and effectively prevent penetration, forming the physical basis for the safety of laminated glass.
  • Optical Transparency: Extremely high light transmittance in the visible light range, without affecting driver visibility or building lighting.
  • Aging Resistance: Maintaining its mechanical and optical properties even under harsh environments such as ultraviolet radiation, humidity, and temperature variations.

 

 

2. Core Applications and Functions in Automotive Glass

Automotive glass is one of the earliest and most important application markets for PVB resin. PVB plays a dual role in automotive windshields, providing both safety and functionality. CCP PVB B-18FS, combined with plasticizer 3GO and additives, can be extruded to produce various PVB interlayer films for architectural and automotive applications.

2.1 Collision Safety and Fragment Retention

This is the most critical role of PVB in automotive applications. In a vehicle collision, the windshield shatters, but the PVB interlayer can:

  • Prevent Penetration: The windshield is designed to take in impact energy. This stops things like stones from getting through the glass into the car. Plus, it keeps passengers inside the car and protects them from head injuries if they hit the glass.
  • Fragment Retention: Firmly adhere to broken glass, preventing sharp fragments from flying and causing secondary injuries to passengers.

2.2 Noise Reduction and Sound Insulation Performance

Modern cars need to be more comfortable to drive. PVB films, mostly those made in a specific way, are good at quieting high-frequency vibrations. This cuts down on wind and road noise. For instance, Changchun PVB B-17HX is made with certain plasticizers and a specific molecular weight to improve its damping abilities. It works very well for car side windows and sunroofs, where better sound insulation is needed.

 

3. Applications of PVB Resin in Architectural Glass

Laminated glass is used in a lot of construction projects. You can find it in curtain walls, skylights, interior walls, and railings. The application of PVB resin must adapt to more stringent requirements for structural strength, durability, and climate change mitigation.

3.1 Structural Safety and Disaster Resistance

The main function of laminated glass in architecture is to provide structural integrity and disaster resistance.

  • Storm and Earthquake Resistance: In severe weather, like hurricanes, typhoons, or earthquakes, PVB laminated glass can still hold its structure even if it breaks. This helps keep people and property inside safe, because the glass doesn't collapse or fall apart.
  • Theft and Explosion Protection: Thickened multi-layer PVB laminated glass (usually a composite structure of multiple layers of PVB and glass) has extremely high impact resistance. It can effectively resist the impact of blunt objects or gunshots and is widely used in high-security locations such as banks, jewelry stores, and museums. In the shock wave of an explosion, the PVB layer can absorb energy, preventing glass shards from injuring people.

3.2 Energy Saving, Environmental Protection, and Aesthetic Design

Technological advancements in PVB films have also made them part of building energy-saving solutions.

  • Solar Control PVB: PVB films containing special additives or dyes can regulate the transmittance and reflectance of sunlight, reducing heat entering the interior (lowering U-value and SC value), thereby reducing air conditioning energy consumption.
  • Colors and Patterns: PVB films can be customized in a variety of colors and can even be embedded with patterns or textiles, providing architects with a wealth of facade design and aesthetic choices to meet the complex needs of modern architecture for light, privacy, and appearance.

3.3 Durability and Long-Term Performance

Architectural glass must withstand decades of outdoor exposure. PVB resin possesses excellent durability:

  • Aging Resistance: High-quality PVB films have good resistance to ultraviolet rays and moisture, ensuring that laminated glass will not yellow or delaminate during long-term use.
  • Edge Sealing: The edge bonding strength between PVB and glass is key to preventing moisture and air penetration, which is essential for maintaining the transparency of laminated glass and preventing internal fogging.

 

As the automotive and construction industries increasingly demand higher standards of safety, environmental protection, and functionality, PVB resin technology is constantly evolving:

♦ Competition and Integration of Innovative Materials

  • While PVB remains the mainstream material, new interlayer materials such as ionic polymers (e.g., SGP/Surlyn) are competing in applications requiring high structural strength and rigidity, particularly in high-rise buildings. The future trend may involve the composite use of PVB with other polymers to achieve a superior performance balance.

♦ Intelligentization and Integration

Future automotive and architectural glass will be more intelligent, with PVB films serving as carriers for functional materials:

  • Thermal Management and Electrical Heating: PVB layers can integrate micro-wires or transparent conductive materials for defogging, defrosting, or intelligent dimming of glass.
  • Integrated Antennas and Sensors: Integrating vehicle antennas or various environmental sensors into the PVB film layer achieves high functional integration and aesthetic optimization.

♦ Sustainable Development

  • Under environmental pressures, developing PVB resins synthesized from renewable resources or bio-based raw materials, and improving PVB recycling technologies, will be significant challenges and development directions for the industry.

Long Carbon Fiber Reinforced PPS

High-performance thermoplastic composites can replace metals. Although PEEK is regarded as the benchmark for engineering performance, reinforced PPS offers a truly cost-effective alternative.

Long Carbon Fiber Reinforced PPS

The demand for engineering thermoplastics such as PC and high-performance thermoplastics like PEEK is steadily increasing in industrial applications. These materials, when produced in the form of 3D printing filaments, offer lightweight alternatives to metals for industries such as aerospace and energy.

By incorporating reinforcements, the properties of these high-performance plastics can be further enhanced. For example, the addition of chopped carbon fibers improves both strength and stiffness. Such reinforcements can be applied not only to low- and mid-range engineering plastics but also to high-performance thermoplastics. As long as the 3D printer nozzle can handle abrasive materials, these composites can be printed as easily as standard thermoplastics.

However, a major drawback of high-performance composites such as reinforced PEEK is the high cost of the required 3D printing hardware. These materials demand extremely high extrusion and chamber temperatures, and the equipment capable of meeting these requirements often costs six figures—undermining one of the key advantages of plastic 3D printing: cost efficiency.

This article explores carbon fiber reinforced PPS as an alternative that delivers performance comparable to metals and PEEK, while offering significant advantages in temperature requirements and overall cost.


Introduction to PPS

What is PPS?

Polyphenylene sulfide (PPS) is a semi-crystalline thermoplastic commonly classified as a high-performance polymer, alongside materials such as PEEK and PEI. It is widely used in machining, mold manufacturing, and additive manufacturing due to its excellent mechanical strength, superior heat resistance compared to standard and engineering thermoplastics, and inherent flame retardancy.

One of the most remarkable properties of PPS is its outstanding chemical resistance. It can withstand a wide range of acids, bases, and solvents, and even shows partial resistance to strong oxidizing agents under certain conditions. However, for particularly aggressive oxidizers such as chlorine dioxide, additional coatings or linings may be required for protection.

With its exceptional performance and more affordable cost compared to PEEK, PPS has found broad applications across various industries. Its mechanical and chemical durability make it ideal for automotive, energy, and chemical processing sectors, while its flame-retardant and self-extinguishing characteristics make it a preferred material for electrical and electronic components, such as surface-mount devices (SMT), motor housings, and transistor encapsulations.

Beyond being an outstanding thermoplastic, PPS is also a reliable replacement for metals such as steel and aluminum. Its thermal stability and chemical resistance enable it to perform effectively in harsh chemical environments, offering strong protection against corrosion and automotive fluids.


PPS as a Composite Material Solution

Reinforced PPS

To improve its strength and rigidity, PPS is often reinforced with chopped carbon fibers or glass fibers, resulting in composite materials with enhanced performance. In fact, PPS is more commonly available in a filled form rather than unfilled.

Researchers have noted that “the addition of carbon fibers significantly enhances the mechanical properties, tribological behavior, post-fire structural integrity, as well as the electrical and thermal conductivity of PPS blends and composites.”

Introduction
PEEK (Polyether Ether Ketone) is a linear aromatic high-performance polymer with repeating units of –O–Ph–O–C(=O)–Ph– in its molecular backbone. It is a semi-crystalline thermoplastic and a high-performance specialty engineering plastic with numerous advantages over other specialty plastics.

PEEK Structure

PEEK has a melting point of 334 °C, a softening point of 168 °C, and a tensile strength of 132–148 MPa. It exhibits excellent mechanical properties, high-temperature resistance up to 260 °C, good self-lubrication, chemical resistance, flame retardancy, peel resistance, wear resistance, and radiation resistance. It can be used in high-end mechanical, nuclear, and aerospace applications. It can also serve as a high-temperature structural material and electrical insulation material, or be compounded with glass fiber or carbon fiber to produce reinforced materials. PEEK is synthesized through a condensation reaction of 4,4′-difluorobenzophenone and hydroquinone in the presence of an alkali metal carbonate, using diphenyl sulfone as a solvent.

PEEK Polymer Structure

Properties of PEEK Resin

PEEK plastic raw materials are aromatic, crystalline thermoplastic polymers with a melting point of 334 °C. They exhibit high mechanical strength, high-temperature resistance, impact resistance, flame retardancy, acid and alkali resistance, hydrolysis resistance, wear resistance, fatigue resistance, radiation resistance, and excellent electrical properties.

High-Temperature Resistance

PEEK resin features a high melting point (334 °C) and a glass transition temperature of 143 °C, with a continuous use temperature of 260 °C. Grades reinforced with 30% glass fiber or carbon fiber have a heat deflection temperature as high as 316 °C.

Its hydrolysis resistance prevents dimensional changes caused by moisture absorption, unlike common plastics like nylon.

Electrical Insulation

PEEK exhibits excellent electrical insulation properties over a wide temperature range, with low dielectric loss even at high frequencies.

Radiation and Peel Resistance

PEEK resin has good radiation and peel resistance, making it suitable for specialized electrical wires. It can be used in sterilizers and wireless verification systems, providing performance comparable to stainless steel.

Exceptional Performance

  • Outstanding high-temperature performance: continuous use up to 250–260 °C, short-term exposure up to 300 °C.
  • Very high stiffness, tensile and compressive strength, and impact resistance.
  • Excellent flame retardancy: inherent flame retardancy, low smoke and low toxicity.
  • Resistant to almost all organic and inorganic chemicals (except highly corrosive agents like fuming sulfuric acid, nitric acid, or dichloromethane).
  • High dielectric strength and excellent insulation properties.
  • Superior wear resistance and low friction coefficient.

Applications

As a high-performance semi-crystalline aromatic engineering plastic, PEEK can replace metals and ceramics in many demanding applications. Its high temperature resistance, chemical stability, mechanical properties, dimensional stability, low thermal expansion, wear resistance, and self-lubricating properties make it ideal for aerospace, mechanical, petroleum, chemical, nuclear power, and railway industries. Even under 200 °C steam, its tensile strength, mass, and appearance remain stable. It has excellent fatigue resistance under high alternating stress, long-term load-bearing capability, flame retardancy, self-extinguishing property, and environmentally friendly combustion (halogen-free, UL94 V-0, oxygen index 24–35).

PEEK is only soluble in concentrated sulfuric acid and nitric acid; otherwise, it is chemically stable, though insufficiently crystallized PEEK may develop cracks in certain solvents like chlorinated hydrocarbons.

Processing

PEEK can be processed via injection molding, extrusion, blow molding, or compression molding. For small-batch or prototype PEEK components, machining from rods or sheets is preferred. Machining should use carbide or diamond tools due to PEEK's wear resistance. Pre-annealing the material can relieve residual stresses, and post-machining stress-relief treatment is recommended to prevent local stress buildup during processing.

PEEK Processing

Current Uses

PEEK is widely used in electrical insulation (wires, flexible PCBs), mechanical components, chemical equipment, nuclear engineering, oilfield connectors, valves, heat-resistant or corrosion-resistant coatings, and in sterilizers and wireless verification systems, sometimes serving as a stainless steel alternative. Its exceptional combination of properties continues to make it a high-demand material across multiple advanced industries, including aerospace, automotive, electronics, medical, and food processing.

How does a pile of loose ceramic powder transform into a final product with complex shapes and precise structures? All of this is thanks to a key manufacturing step: forming.

Today, we will clearly explain three main ceramic forming methods, exploring their working principles, advantages, disadvantages, and typical applications.

1.Dry Pressing

This is the simplest and most common method, very suitable for the mass production of simple-shaped parts.

Working Principle: Ceramic powder mixed with a small amount of binder is filled into a metal mold. Then, high pressure is applied via upper and lower punches to compact the powder into a dense "green body".

Advantages:

High Efficiency: High degree of automation and fast production speed.

Uniform Dimensions: Excellent product consistency.

Low Cost: Suitable for large-scale production.

Disadvantages:

Difficulty in manufacturing complex shapes (e.g., parts with side holes, thin walls).

High mold cost.

Possible uneven density in the green body.

Typical Applications: Ceramic seal rings, gaskets, substrates, bricks, tiles, etc.

 

Dry Pressing

 

2. Isostatic Pressing

Isostatic pressing was developed to solve the density uniformity issues of dry pressing. It uses a liquid or gas as the pressure-transmitting medium to compress the powder uniformly from all directions.

Working Principle: Ceramic powder is loaded into a flexible rubber or plastic mold, which is sealed and placed into a high-pressure vessel. Pressure is applied via a high-pressure pump, uniformly compacting the powder.

Advantages:

Uniform Density: The properties of the green body are consistent in all directions, which is key for manufacturing high-performance ceramics.

Good Shape Capability: Can produce parts with relatively complex shapes.

Disadvantages:

Large equipment investment.

Production cycle is longer than dry pressing.

Relatively low dimensional accuracy, often requiring subsequent machining.

Typical Applications: Large crucibles, high-voltage electrical insulators, spark plugs, high-performance structural components.

3. Injection Molding

If you need to manufacture ceramic parts with highly complex 3D geometries, similar to metal or plastic parts, injection molding makes this possible.

Working Principle: A large amount of ceramic powder is mixed with a thermoplastic binder and plasticized upon heating. It is then injected into a sealed mold cavity using a screw. After cooling and solidifying, it is demolded to obtain the "green body". Subsequent debinding processes are required to remove the binder before sintering.

Advantages:

Extremely high shape complexity and dimensional accuracy.

Automated production, high efficiency.

Good product consistency.

Disadvantages:

The debinding process is very slow and prone to causing defects.

High cost of molds and equipment.

High raw material cost.

Typical Applications: Micro ceramic gears, engine turbine rotors, medical surgical tools, electronic packaging components, etc.
